Application filed November V2, 1922', A Serial No'. 1598,578.y i i To all whom t may concern:

Be it known that I, CLYDE W. MUMMERY, a citizen of the United States, residing at Richmond, in the county of Macomb and State of Michigan, have invented certain new and useful Improvements in Burners, of which the following is a specification..

This invention relates to burners especially adapted and intended for burning kerosene or other hydrocarbons'without the use of a wick, and it is adapted and intended for use on oil stoves or the like.` 1 j n TheV object of the invention is to provide improved means for vaporizing the oil orgenerating a vapor which is burned in a combustion space located above the vaporizer. A feature of the invention is the introduction of air into `the oil where it is fed `into the generating trough, together with means forvsupplying additional heat to the point of inlet to theV trough, whereby complete vaporization is effected and carbomzation is prevented. y

Further objects of construction in the details of theburnerwill be apparent from the following description and the accompanying drawings in which Fig. l isa verti-y cal ysection of the burner. Fig. 2 is a section on the line 2 2 of'Fig. 1.` Figg is a detail `in section of the'inlet valve structure.

The base of the burner consists of an annular trough 2, in which vaporization is effected, the casting of, which the trough is formed having a'fcentral air opening S. This trough supports innerl and outeryperforated shells 9 and 4 the lower edges vof which rest inmachined seats formedin the inner and outer edges of the trough'respectively, the shells or tubes being spaced apart to form van vannular combustion chamber communi-v cating with the trough below. The linner combustion tube 9Vis closed at the top -asv shown at 10, and the shells are surrounded by an outer casingor wall phaving air holes 11 around the same near the top, for the purpose of admitting additional air tothe upper part of the burner. The shells are spaced and held in proper positionby means of screws Gwhich extend throughthe casing 5 and perforated wall 4` and project inwardly to substantial contact with the inner combustion wall to guide the latter i and center it in position. j The fuel oil used is fed to the trough from any suitable source of supply thru a nipple 12 f on agneedle valve casing 1, the needle casing and provided with a handle 131 whereby` it may be operated. This casing 'is y connected by-'a union 14 with a bored boss l5 cast on the side of the trough. The valve casing l, slightly inside or beyond the valve seat has a bored boss 16 for the connection of a pipe 17 which is providedat its upper end with a priming cup '18 having a lid 19, and the upper edge of this priming cup is notched asindicated at 3 to form an air inlet. l j 4 Extending inwardly from the boss 15'is a rod or finger 20 which projects upwardly in the outer casing 5, and preferably in contact with the former. The purpose of this rod is to conduct heat to the oil passage in the boss 15, at about the point where said oil flows intothevaporzing trough, to assist in va'- porizing the'oil. c

lnthe operation of the into the trough and belightedfby a match to heat the parts and start generation. The needle valve is thenopened and vapor is generated and is consumed in thel space between the walls 9 and 4, air being supplied from the inner and outer sides thru the perforations in said walls. In the operation the vaporization causes an inflow of air thruthe notch inlet 3 in the priming cup, and this air passes thru the pipe 17l and mixes with' the oil which is fed into the v j burner,-it is primed f by introducing a yquantity of starting fluid into ,the priming cup l18, whence itvflows vaiveiabeing tapped into the maar the vaporizing trough. Also heat is conducted the rod'20 to the vaporizing trough,par ticularlyfat-the point of inlet, land the heat so conducted, as well as'the supply of heated air,y greatly assists the vaporization and pretrough, spaced perforated walls'v mountedv thereon and forming a combustion chamber 70 the 'space between the combustion wall 4 and f pipe.

above the trough, an inlet pipe to the trough,

and a rodV projecting upwardly from 'the i inlet' pipe, besideftlie 'outer of said Walls,

and serving` to conduct heat to said inlet 2. In aburner, a vaporizlng trough'provided with an inlet pipe, a pair or perforated shells standing on said trough and spaced apart to form a combustion chamber above IDt-lie trough, and a heat Conducting projection extending from the inletpipe upwardly be# side the outer of said shells, tokconduct heat therefrom to said inlet pipe.
